To all whom it may ccncem:

Be it known that I, lViLLIAM J. Momma, a citizen of the. United States, residing at Wyoming, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Bags, of which the following is a specification.

My invention relates to improvements in bags as articles of manufacture.

The object of my invention is to form a bag in such shape as to reduce the amount of material required for its construction without reducing the capacity of the bag, thereby reducing the cost, and to produce a bag which is convenient to tie and easier to empty into receptacles with less danger of spilling than otherwise.

My invention consists in forming a bag of triangular truncated construction, the edges of the bag tapering from the bottom upwardly to a contracted neck or mouth at the top, and in the article of manufacture as set forth and claimed.

Heretofore the common method of constructing bags was to make them substantially rectangular from top to bottom with a mouth or opening at the top extending the entire width of the bag, thus requiring a large amount of the bag to be used in tying. By means of my invention, by so cutting the material as to gradually reduce the size of the bag from bottom to top, I am enabled to maintain the original capacity of the rectangular shaped bag with the use of much less material than is required in said rectangular shaped bags, thereby effecting a great saving in the material and cost, and producing a bag which is much easier to tie, as well as one which may be emptied into receptacles without danger of spilling.

In the accompanying drawing Which serves to illustrate the construction and use of my invention:

Figure 1 is a diagrammatic view of material showing be out without waste.

Fig. 2 is a side view, showing the shape of the bag after it is sewed or stitched.

Fig. 3 i a perspective view showing the bag filled with material and tied.

Fig. 4 is a top view of Fig. 2.

Fig. 5 illustrates in side elevation a modification of my bag.

In the manufacture of bags in accordof a strip how the material may ance with my invention, I preferably take a strip of material 1 of the required width and cut it into parts 2 and 3, in the manner shown in Fig. 1, the parts 2 being formed large at the center and tapering toward each end. The parts 2 are then folded in the manner shown in Fig. 2 and the tapering edges secured together by scams 4 to form a bag with a contracted neck, as shown in said figure. The parts 3 are cut in two at the center or narrowest part, and the pieces thus formed are sewed together in a inanner similar to that shown in Fig. 2, except that it is also necessary to join the two parts together with a seam across the bottom, but the bag will be of substantially the same size and shape as when formed from the parts 2. Each bag as thus formed is provided with a contracted neck or mouth 5, and there is substantially no loss or waste of material in thus cutting the parts for the bags.

A substantial amount of goods is saved in the construction of each bag thus formed. The bag may be filled through the mouth 5 and then tied as illustrated in Fig. 3, or it may be first tied in that manner and then filled through an opening provided with a valve at the other end of the bag, in the manner that cement bags are now commonly filled.

The bags made in accordance with my invention are preferably constructed of canvas or burlap, but may be made of any flexible material such as paper, duck or the like. These bags so constructed are especially adapted and intended for use as cement bags, but they will also be valuable as wheat sacks, and may be formed of paper or similar material to great advantage for flour sacks, and for other purposes.

My invention is capable of some modification without material departure from its spirit or scope, as for instance, instead of having the bag tapering on each edge from its closed to its open end, as shown in Fig. 2, it may be tapered on one edge only, as shown in Fig. 5, forming the contracted neck or mouth 5. In making this form of bag the material is preferably cut in the manner shown in Fig. 1 in the shape of a truncated triangle, as shown by the part marked 3 and then folded on the dotted line 3" to form a bag similar to that illustrated in Fig. 5. The seam in this form of bag will be at the bottom and upon the tapered edge. This construction would probably afiord greater economy in the piling of the bags, especially in the ends of square receptacles, as by placing the small end of one bag adjacent the large end of the adjacent bag, all of the space will be utilized. The

great significance and value of this invention will be appreciated when the vast extent and importance of the bag industry is known, and, the saving in material effected in the construction of each bag, together with its convenience in use as heretofore pointed out, renders this article one of great merit and value.

' In addition to the various other advantages of my invention when the bag is used for cement and the lilze and it is desired to close the opening by sewing as is commonly done, after the bag has been filled, a great saving in labor i effected by having a com- Conies of this patent may be obtained for paratively small opening (such as is obtained by my invention) to sew up.

I claim:

A plurality of bags out from a given strip of material, each bag having, when completed, an outwardly extending contracted hollow elongated neck, the cut-away portion made in forming the outwardly extending contracted hollow elongated neck upon one bag forming the bottom of a bag cut away from an adjacent portion of said strip, whereby there is' no waste of material in the cutting and forming of said bags, and whereby bags of greater capacity, when tied shut are formed out of a given amount of material than otherwise.
